The aim of the study was to quantify and compare apical debris extrusion in two systems of continuous and reciprocating rotary instrumentation with, and without, the use of a patency file. An experimental study was carried out in 120 mesial roots of lower first molars, which were randomized in the follow...
Objetivo: conhecer as principais práticas adotadas atualmente por cirurgiões dentistas, clínicos gerais e endodontistas na realização do tratamento endodôntico. Material e Métodos: um questionário contendo 21 perguntas de múltipla escolha foi enviado para os profissionais, nas cinco regiões do ...
Estudos moleculares ressaltam as limitações do protocolo endodôntico tradicional em eliminar bactérias dos canais radiculares. Apesar do preparo químico-cirúrgico (PQC) promover uma drástica redução bacteriana, muitos canais continuam infectados após essa etapa do tratamento. Dessa forma, estud...

Abstract Objective: This in vitro study aimed to compare the efficacy of irrigants using various irrigation activation methods to the push-out bond strengths of fiber post to root canal luted with self-adhesive resin cement (SARC). Methodology: Forty-eight decoronated human canines were used. The speci...

Abstract In order to evaluate the volume of dentinal cracks taking into account the age of the dentin and the type of file system used for endodontic procedures, forty freshly extracted single-rooted lower incisive teeth presenting similar root volume, were divided into two groups according to the age of...
RESUMEN: La creencia de que el tratamiento de endodoncia es el tratamiento dental más doloroso es algo habitual. A pesar de ello, la percepción intraoperatoria durante el tratamiento de endodoncia ha sido poco estudiada. Por ello, el objetivo de esta investigación fue describir la percepción de dolor...
Abstract This study evaluated the amount of apically extruded debris after chemo-mechanical preparation (CMP) using positive and negative pressure irrigation systems [Conventional irrigation (CI) and EndoVac (EV)] in association with different irrigants [6% Sodium Hypochlorite (NaOCl), 2% Chlorhexidine g...
The aim of this study was to observe the penetration of an aqueous solution into the root canal dentin under sonic activation and ultrasonic activation. Materials and Method: this study consisted of experimental in vitro research. In order to achieve a closed system, the apex of 45 single-rooted teeth wa...
Abstract: Chemomechanical preparation is intended to clean, disinfect, and shape the root canal. This step is of utmost importance during treatment of infected teeth with apical periodontitis, because treatment outcome depends on how effectively the clinician eliminates bacteria, their products, and necr...
